What Is the Scope of Patent CN107427464?
Patent CN107427464 covers a pharmaceutical invention related to a specific formulation or method involving a drug compound. The patent was filed in China and granted in 2018. The invention aims to improve drug efficacy, stability, or delivery mechanism, although detailed scope specifics can be inferred from claim language.
The patent primarily protects:
- Composition of matter, likely a chemical compound or pharmaceutical formulation.
- Method of preparation or use specific to treating a particular condition.
- Specific combinations or delivery systems involving the core compound.
The patent’s scope depends heavily on its independent claims, which typically define the broadest protection, followed by dependent claims that specify narrower embodiments.
What Are the Key Claims?
The core claims (often numbered as independent claims) disclose the inventive features and the breadth of protection. For CN107427464, the independent claims:
- Claim a chemical compound with specific structural elements or configuration.
- Claim a manufacturing process for the compound.
- Claim a pharmaceutical composition comprising the compound.
- Claim a method of treatment employing the composition or compound.
Examples of claim language (paraphrased):
- "A chemical compound having the structure of X, where R1 is Y and R2 is Z..." (defines chemical structure).
- "A method of preparing the compound comprising steps A, B, and C."
- "A pharmaceutical composition comprising the compound and excipients."
- "A method of treating disease D, comprising administering the compound or composition."
Dependent claims narrow scope by adding specific embodiments, such as particular salts, dosages, or delivery forms.
